After splitting time with Keith Pankey at one of the outside linebacker spots for two seasons, Roberson has found a home at weakside linebacker, with Pankey slotted in as the strongside linebacker.

He is being counted on to be a playmaker.

"We talk about it all the time, how nice it is that we don't have to rotate this year,'' said Roberson after Wednesday's morning practice.

"It's nice to just have your own side and to be able to get into a groove and stay in a groove.''

So who is the better player, Roberson or Pankey?

Do they ever argue about it?

"I think we're two different players and when we work together, it's a good thing,'' said Roberson. who was honorable mention all-Pac 10 last season after making 55 tackles, including 7 1/2 tackles for loss with two sacks.

"I don't think one of is is better than the other. I think we both have our talents,'' said Roberson.

Roberson has enjoyed an up-close view of the position battle at middle linebacker which seems to be primarily between sophomores Tony Wilson and Rueben Robinson.

A position where there was no concern a few months ago - before David Pa'aluhi left the program - has turned into a nail-biter.

Roberson said Monday, "I don't know what they're going to do. I think Tony and Rueben have both made big strides in camp. ... I have chemistry with both of them. I think they both understand enough that they can communicate with me and Keith.

"It might be a rotation thing,'' said Roberson. "It might be the same thing that me and Keith did, or they might just start one over the other. We don't know yet.''
